System survey
Principle Gateway types AKA 241, AKA 243 and AKA 244 are system components to be used in conjunction with
controllers in the ADAP-KOOL® series of controls for refrigerating systems.
When the gateway is used it is possible to build complex control systems with alarm moni toring and
data logging into decentralised refrigerating plant.
All controllers in the AKC series are linked up in a two-core data communication system that is
registered under the name DANBUSS Data Communication System.
A Gateway is the control unit used when the data communication system has to be connected to a PC,
a printer, a TCP/IP server or a modem.
Example Operation of gateway and the controllers in ADAP-KOOL®
refrigerating systems is performed with control panel type AKA 21
or with system software type AKM (installed on PC).
The control panel is connected to the two-core data
communication cable at any random point. After that, all settings
and adjustments pertaining to the day-to-day operation of the
system can be made.
Cold rooms and refrigeration appliances are regulated by AKC 72A
and AKC 114-116.
A gateway type AKA 244 is attached to the data communication
system and connected to a modem or printer.
If a PC is to be used in the actual system, one more gateway will
have to be connected. This gateway may also be an AKA 244, but
if the gateway is required for simple operation of the system, the
smaller type AKA 241 may be employed.
The printer can make printouts of all alarm reports registered on
the refrigeration system by the AKC controllers.
If the alarms are to be transferred to the security centre or to the
refrigeration company’s PC or printer, it must take place via the
modem connection.
Log data can be collected from all connected controllers. This data
may then be picked up by a PC and displayed.
Log data can also be stored as documentation for correct tempera-
ture behaviour (demands to temperature registration on the part
of the authorities).
The same functions can be carried out with gateway type AKA 243, but here it is also possible to com-
municate with other control lers via the LonWorks output. The output will primarily be connected to
controllers from the EKC 200, 300, 400, 500 or AK 2 series.

AKA 21
When mounted, AKA 21 is connected for setting of address, etc.
DANBUSS
Here there is a DANBUSS connection from one of the other units in the system.
The input is galvanically separated from the remaining circuits.
On an AKA 243 the DANBUSS address must be set between 61 and 125.
On an AKA 244 the address may be from 1 to 125.
LON (AKA 243 only)
Here the data communication is connected to controllers with a LONWORKS® - FTT10 or RS 485 inter-
face (eg EKC 200, 300, 400, 500 or AK 2 controllers). The connection is described in a separate docu-
ment bearing literature number RC.8A.C.
On this input the connected EKC controllers must have addresses from 1 to 60 and AK 2 controller
1-10.
RS 232 / PC / TCP/IP
Used for connection of a PC, a modem or a TCP/IP server. Only one of these can be connected. Which
one can be defi ned with a setting in the gateway.
Printer
A printer is connected here.
Only printers with parallel interface can be used.
The two relay outputs DO1 and DO2 and the two inputs DI1 and DI2 have in this manual been described
with the most frequently used function. If you wish to use an input or an output diff erently, it must be given
a new confi guration. For this purpose system software type AKM must be used. Cf. the AKM manual.
Relay outputs (D01, D02)
AKA 243/244 is provided with two relay outputs (SPDT).
The DO1 output is used with modem connection or TCP/IP connection. Via the relay output,
supply voltage is connected to the modem or TCP/IP connection. The DO2 output can be used for
transmitting a joint alarm signal to external equip ment. (DO2 is activated for two minutes when the
alarm handler in the master gateway (address 125) receives an alarm message of status 1 from a
controller).
4 Manual RS.8A.A4.02 © Danfoss 01/2004 AKA 241, AKA 243, AKA 244
When you use the alarm routing function it is possible to select D02 active or inactive within specifi ed
periods of time (cf. section “AKA Alarm Table”).
On/off inputs (DI1, DI2)
AKA 243/244 is provided with two on/off inputs.
Input DI1 is used for the printer’s paper function. DI1 is connected to a contact function which is
operated when the paper has been placed in the printer. (Top of form setting).
The DI2 input is used for manual change-over between “default” and “optional” alarm destinations in
connection with the extended alarm routing in AKA 243/244 (cf. section “AKA Alarm Table”).
Light-emitting diodes
- For each communication gate (RS 232/DANBUSS) there are two light-emitting diodes (LED), one
for sending and one for receiving. The diodes are lit, when there is communication to or from the
gateway.
- The status of the ON/OFF inputs and relay-outputs are also indicated with light-emitting diodes.
- There is an LED for power ON
- AKA 243 also has a LED for LON-communication

Functions of the four The gateway is available in four versions where the ordinary version contains all functions whereas the
gateway types simpler version only contains the few functions required for it to be the connecting link between a PC
and a network of controllers from the ADAP-KOOL® range of refrigeration controls. The ordinary gate-
way can be set for connection with either a PC, a modem or an TCP/IP server.
The third and fourth version has furthermore been provided with LON data communication.

Termination
To obtain correct data transmission, the data transmission cable must be termina ted.
On the PC board next to the DANBUSS connection there are two wire switches which must either be
closed or open, depending on where the gateway is placed in the system.
1) As the last unit on the data
transmission cable:
The wire switches are kept
closed (BUS TERM “ON”)
2) The gateway retransmits the
signal:
The wire switches are opened
(BUS TERM "OFF").

The connection is a LonWorks® interface. AKA 243A = FTT 10. AKA 243B = RS 485.
Cf. separate literature RC.8A.C.
Termination: the wire switch must be closed.
DI1, DI2, DO1 and DO2 The two relay outputs DO1 and DO2 and the two inputs DI1 and DI2 have in this manual been described
with the most frequentlky used function. If you wish to use an input or an output diff erently, it must be given
a new confi guration. For this purpose system software type AKM must be used. Cf. the AKM manual.
Warning! DO1 and DO2 must not be connected to low voltage on one output and high voltage on the other.
Both outputs must have the same voltage level.
Printer The printer port of AKA 243/244 has been designed as a parallel printer port. An ordinary parallel
printer cable is used for the connection.
An EPSON compatible matrix printer can be connected.
The on/off input DI1 is connected to a pushbutton switch (pulse pressure with spring return).
When you push the switch, a signal is sent to AKA 243/244 that the printer is ready and that the paper
is correctly placed.
AKA 241, AKA 243, AKA 244 Manual RS.8A.A4.02 © Danfoss 01/2004 9
Manual change-over of ON AKA 243/244 you may change manually between two diff erent alarm routes. The DI2 ON/OFF
alarm routing input can be connected to a contact function. When the DI2 input is cut in, the alarms will be sent via
route 2 (optional des ti nations). (Cf. section “AKA Alarm Table”).
Alarm relay On AKA 243/244 the DO2 output may be used for connecting an alarm function. There is connection
between terminals 13 and 14 when the gateway is energised and there is no alarm. This connec tion is
interrupted for two minutes when a status 1 alarm is received from a control ler, or if the supply voltage
to the gateway fails.

Battery The gateway is provided with battery backup securing the settings and log collections.
3 V
CR2032
When the battery needs to be replaced in a AKA 243 or 244, an alarm message is sent.
When a battery is replaced, make sure that the supply voltage is not removed from the gateway. If the bat-
tery and supply voltage are both removed at the same time, the clock setup, log setup, collected log data,
master control setups and possibly EKC installation data will all be lost.
